The TI-1750-III carries a famous name, it seems to be the successor of the first TI LCD calculator, the TI-1750
TI-1750-III_PCB.jpg (70848 Byte)Well, to be honest to you, under the hood this calculator is nothing else than another design of the original TI-1030 calculator. Not as exciting as the TI-1760 DataCard.
The same housing was used for the Time Manager sporting an integrated clock with two 24-hour alarms and a stopwatch.

If you compare the suggested retail price (SRP) of three (internaly identical) calculators you'll notice:

$10 TI-1001
$12 TI-1031
$15 TI-1750 III

That's the power of marketing!
